RUBBER HEEL.

2'2/ au I07mm t may concern:

Be it known that I, EVERETT T. PACKARD, a' citizen of the United States, residing at Avon, in the county of Norfolk, in the State of Massachusetts, havev invented a certain new and useful AIniproveiiient in Rubber Heels, of which the following is a specification, reference being had to the accompanying drawings.

The immediate object of this invention is to'provide an inexpensive, but particularly serviceable spring heel in which special pr'ovision is iliade for reinforcing the heel, and for preventing the undue wearing 'of the rubber at the several points where the nails pass through the heel as well as for preventing the undue lateral deflection, or stretch, of the rubber when the heel is in service, as I will explain more fully hereinafter.

A hee] embodying my present improvements is illustrated in and by. the' annexed drawings, Figures l and 2 showing, respectively, bottom and side views of the saine.

Fig. is a transverse sectional view of said licei taken on the line 33 of Fig. 2. In Fig. l I have illustrated, by planl and edge views, one of a pair of reinforcing plates which I embed 1`n the rubber heel at the time the lat/ter is molded. f A

Referring to these drawings the letter a -indicates the heel proper, the saine vbeing "formed mainly of vulcanized rubber, and being of any approved -size and style. In the process of making the said heel I place in the linold a pair of reinforcing plates b-c inade of stiff material, suoli as sheet i.

metal, said plates conforming in shape (when in their operative vpositions in the heel) to the sides and curved rear portion of the heel as is best seen in Fig. 3 ofthe Specification of Letters Patent.

with a plurality of holes (Z which are of such size and so positioned that they may receive nails by means of which vthe heel may be.

fastened to the shoe, and the rear end portion of said plates overlap each other (see- Fig. 43) so that when a nail is passed therethroughthe two plates are, in effect, hinged together and are thus prevented from displacement .with respect to each other. plates are also forniedwvith relatively larger holes e which fill with the plastic rubber mass,l when the heel is being molded and, when the rubber has'been vulcanized, the rubber iii the several holes c seives'to conneet the rubber on the'opposite sides of the plates- Zi-ff and to thus prevent the plates from working loose.

The bottoni face of the heel is spotted as at nl in the operation of molding said heel,

lthe said spots being suitably positionedto register with the openings (l in the concealed plates and so that, when nails are driven into thc heel at the spotted points, said nailsv EVERE'IT T. PACKARD.
